How to delete an Entity and all associated Entities along with it?

Question

Java

Here is an example of Entity, extra methods and fields are omitted.

public class Restaurant extends AbstractNamedEntity {
    @OneToMany(mappedBy = "restaurant", cascade = CascadeType.ALL, orphanRemoval = true)
    private Set<Vote> votes;
    @OneToMany(mappedBy = "restaurant", cascade = CascadeType.ALL, orphanRemoval = true)
    private Set<Dish> dishes;
}

If I delete Restaurant now, then a lot of SQL happens because each Entity is deleted by a separate SQL.
Those. if there is 200 Dish, then there will be 202 SQL.

How can I remove this without spamming SQL queries? I read an article that CascadeType.Remove cannot be used with ToMany associations.

NamedGraph not working, catching ConstraintViolationException

public static final String GRAPH_RESTAURANT_WITH_VOTES_DISHES = "Restaurant with votes-dishes.Graph";
    @Transactional
    @Modifying
    @EntityGraph(GRAPH_RESTAURANT_WITH_VOTES_DISHES)
    @Query("DELETE FROM Restaurant r WHERE r.id=:id")
    int deleteRestaurantById(int id);

Is there a way to do this in one @Query?
